5. 6. Test the connectivity to EM-Controller through backhaul
...
Prerequisites - One Time Process
1. Ensure Extender 1 is running properly with configured vap's of FH and BH.
2. Make atleast 7 feet distance from Ext1 to Ext2
3. Ensure ieee1905_em_agent,onewifi_em_agent processes are running in Ext2
4. Ensure mesh backhaul connectivity is established over 5G through wifi1.1 interface1. Copy below content to /nvram/InterfaceMap.json file.

2. Edit the AL_MAC_ADDR in /nvram/EasymeshCfg.json. Here, wifi0.1 interface mac address as AL_MAC_ADDR
3. Reboot the device
After reboot,
4. Ensure mesh backhaul connectivity is established over 2.4G through wifi0.1 interface.

iw dev wifi0.1.sta<i> station dump ## This command gives information on connected client ie Extender2. |
6. Wait for few minutes( for Agent to propagate SSID information from Controller to OneWifi in Extender2) and then check
7. Set static IP for brlan0 interface in Extender2
Code Block | ||
